Thrust versus turbo size

[stevo]

Hi guy going to have a go at my first turbo charger jet, I have a turbo, a Garrett with a 42mm inducer size can someone tell me what sought of thrust this could produce?

Hi

Not much thrust , maybe 15 lbs - 7 Kgs .............not because of the turbo , simply because of the limited amount of air its flowing , gas turbines need to flow a lotta air , generally ~1 lbs/sec to produce 50 lbs of thrust

Unfortunately small turbos , and a 42mm turbo is a small turbo when talking turbines , invariably have very poor turbine efficiency which reduces potential thrust .

Hope this helps

Cheers

Thanks John looks like I need to find a bigger turbo, I want to be able to move a small moped type bike, don't want to go fast just be able to move about at bike show for fun. Could someone please give me an idea of the size I would need?

Probably something like a GT42 with a 70 mm inducer or Gt40 with a 67mm
